Contractions of the middle ear muscles were elicited by electrical stimulation of the facial and trigeminal nerves in anesthetized cats. The effects of these contractions on cochlear microphonic responses to air-and bone-conduction stimuli were examined. Contractions producing attenuation of air-conduction responses similar to that observe under physiological conditions also produced marked changes in bone-conduction responses. It is concluded that bone conduction does not provide a means of acoustic input control which effectively eliminates middle ear muscle effects.
